4 Claims, No Drawings ZERO-VALENT NICKEL COMPOUND-AMINE CATALYST This is a continuation of application Ser. No. 816,159 filed Apr. 7, 1969, which is a continuation of Ser. No. 582,224, of Sept. 27, 1966, both abandoned.
In US. Patent Application, Ser. Nos. 532,900, filed Mar. 9, 1966, and 76520, filed Dec. 19, 1960, now abandoned, there has been described a process for the catalytic dimerization and trimerization, respectively, of 1,3-diolefins, in which catalysts are used which are produced by mixing carbon monoxide-free compounds of nickel with organometallic compounds such as metal alkyls, metal aryls or Grignard compounds, or with metal hydrides or with metal hydride complex compounds and electron donors. As electron donors, Lewis bases are used, such as cyclic ethers, tertiary amines, especially cyclic tertiary amines, alkyl or aryl phosphines, especially triphenylphosphine or alkyl or aryl phosphite, or compounds with a carbon-to-carbon multiple bond. Similar processes are claimed in German Auslegeschrift 1,126,864 of Badische Anilinimd Soda- Fabrik wherein the catalysts are made by reducing transitional metal compounds by means of metals (Al, Mg) and German Auslegeschrift 1,144,268 where cer tain nickel-(O) compounds are used as catalysts. It is furthermore known that butadiene can be transformed by means of catalysts, such as (R P) Ni(CO)- into mixtures of cyclooctadiene-( 1,5) and 4-vinylcyclohexene, by the methods described in German Pat. No. 881,51 1 and in US. Pat. No. 2,686,209.
It is also known that, according to the Applicants US. Pat. No. 3,088,985, 2,3-dimethylbutadiene-(1,3) can be transformed with the aid of typical Ziegler catalysts into an open-chained trimer, and specifically into a hexamethyldodecatetraene.
It is an object of this invention to provide a novel polymerization process and catalyst therefor.
According to this invention it has surprisingly been found that, when an excess of amines of the type N H Rl/ wherein R and R H and/or alkyl, cycloalkyl, aralkyl or aryl radicals which can be closed to form a ring, are added to the catalysts of zero valent nickel, with and without donors, the oligomerization of 1,3-diolefins can be controlled so that open-chained oligomers are produced.
The invention relates to a process for the catalytic oligomerization of 1,3-diolefins to form open-chain compounds, characterized in that 1,3-diolefins are reacted in the presence of compounds of zero valent nickel and an excess of amines of the general formula wherein R and R are H and/or alkyl, cycloalkyl, aralkyl or aryl radicals, which can be closed to form a ring, with or without other electron donors. Additionally, it has been found that the amine catalysts can be transformed into their alkylene derivatives.
The open-chain oligomers are produced by way of dimerization and trimerization reactions, which are siwherein x is a whole number of about 1 to 5.
In the processofthe invention, the 1,3-diolefins used are suitably exemplified by isoprene, piperylene and especially butadiene-( 1,3). Other 1,3-diolefins can also be used, such as 3-methylheptatriene-( 1,4,6), 2,3-dimethylbutadiene-( 1,3), hexadiene-(2,4), and octatriene-( 1,3,6). Different 1,3-diolefins can also be brought to reaction with one another.
Carbonyl-free compounds of zero valent nickel are preferred catalysts. Aniline, N-methylaniline, morpholine, toluidine or ,piperidine, for example, can be used as amines in the process of the invention.
In accord with this invention there is used an excess of amine. By the term excess is meant a quantity of amine which in admixture with the nickel compound will not be bound to the nickel. Thus, it will be seen that, where the nickel compound has electron donors attached thereto in l to 4 equivalents with respect to said nickel, it mayor may not be possible to bond additional electron donors to the nickel. For example, 11- nickel (O) mono (triphenyl) phosphite is capable of adding three further electron donor equivalents. Amines are generally considered electron donors and so, in the above example, the nickel can have added thereto three equivalents of amine. In this case by excess amine there is meant more than three equivalents. However, in the case of 1r nickel (0) tetra(triphenyl)= phosphite, the nickel cannot add any further electron donor equivalents. Therefore, any amount of amine would be an excess.
It is not known exactly what interaction, if any, there is between the excess amine and the nickel compound. It may be that the excess amine replaces other electron donor equivalents or it may be that the excess amine remains free.
In addition to the oligomerization by which open chain compounds are formed, there also occurs to some extent the cyclization reaction which would be the principal reaction if amines were not added. It is therefore observed that a cocylization of butadiene and the open-chain oligomers that develop according to this process, such as n-octatriene-( 1,3,6), takes place:
3-(butene-(2)-y1-(1)).. cyc1oocta liene(1,5)
The process of the invention can be performed in the presence of solvents, but only of those solvents which do not attack the catalysts or the organometallic components or metal hydrides which are used for the manufacture of the catalysts. Aliphatic or aromatic hydrocarbons or aliphatic or cycloaliphatic ethers are preferred. There is a special advantage, however, in using as solvents the diolefins used in the manufacture of the catalyst or the products which can be manufactured according to the process of the invention, so that no foreign substances will have to be separated from the reaction product. The process can be performed at normal pressure or at overpressure, the pressure range being determined by the desired direction of the reaction and the temperature that is necessary in each case. The process can be performed at temperatures of -l to +200C., but preferably at from 20 to 120C.
The products that can be manufactured according to the invention are valuable materials for further organic syntheses. The products are of especial value as components for the manufacture of so-called terpolymers, i.e., elastomers composed of two monoolefins and a third component which has at least two double bonds.
EXAMPLE 1 4.4 g 17.1 mmoles of nickel acetyl acetonate and 10.9 g 17.1 mmoles of tri-(phenyl-phenyl)-phosphite are reduced at 0 to 20C., in 85 ml of benzene in which about g of butadiene are dissolved, by means of 4.4 g =34 mmoles of monoethoxy diethyl aluminum. 100 g of morpholine are added to the catalyst solution which is then heated to 80C. with the introduction of butadiene. In the course of 70 minutes of intense agitation a total of 870 g of butadiene is absorbed. All volatile products are then removed by distillation in a vacuum increasing towards the end to 10' to 10' torr, and at a bath temperature of 80C. The composition of the distillate is determined by gas chromatography. A total of 866.5 g of product is obtained, having the following composition:
84.1 g 9.7% of n-octatriene 8.7 g 1.0% of 4-vinylcyclohexene 326.9 g 37.3% of cyclooctadiene-(1,5)
69 g z 8% d t t 109.2 g 126 f odeca e raene the 1,3,7 isomer. With maleic acid anhydride :1 1:1 addition product (C H O is obtained (MP. 7273C.).
The dodecatetraene fraction consists of three different isomers whose structure has been able to be deter- 4 mined both on the basis of the H NMR and infrared spectra and through the formation of addition products with maleic acid anhydride. They are the following compounds:
c-o-cw c-c-c c-c-c-c c- (Ice- 1) (Iw-c -n) The hydrogenation of the isomer mixture yields ndodecane as well as 5-propylnonene.
The 3-(butene-(2)-y1-( l))-cyclooctadiene-(1,5) was identified by means of a comparative test. When hydrogenated it yields n-butyl-cyclooctane. 1n the hydrogenation product of the higher hydrocarbons it has been possible to detect n-octyl-cyclooctane and other compounds.
EXAMPLE 2 The catalyst is prepared according to Example 1, but 4.5 g 17.1 mmoles of triphenylphosphine are used as the electron donor. The reaction is performed under the same conditions and 612 g are obtained of a reaction product having the following composition:
61.2 g 10% of n-octatriene 4.7 g 0.8% of 4-vinylcyclohexene 10.0 g 1.6% of cyclo0ctadiene( 1,5)
32.2 g 5.3% of cyclododecatriene-(1,5,9)
163 g 26.6% of C to C hydrocarbons 21 g 3.4% of higher isomers.
The high content of dodecatetraenes is to be explained by the fact that the n-octatriene reacts in turn with butadiene.
} -of dodecatetraenes EXAMPLE 3 The catalyst is prepared according to Example 2, but in only half the amount, and 40 g of morpholine are added. The catalyst solution is mixed with 900 g of butadiene and the solution is pumped through a reactor consisting of a copper capillary having a reaction capacity of 2 liters and lying in a bath heated to 80C., the time of stay being minutes. At the end of the capillary is a pressure relief valve set for a discharge pressure of 30 atmospheres. In this manner, 504 g of a reaction product is obtained having the following composition:
285 g 56.5% n-octatriene 15.1 g 3.0% 4-vinylcyclohexene 77.6 g 15.4% cyclooctadiene-(1,5)

6.7 g 1.3% trans, trans. cislcyclododecatriene- 1,5,9)
9.5 g 1.9% higher oligomers The yield of n-octatriene amounts to 96% of the products produced by hydrogen transfer.
EXAMPLE 4 One tenth of the amount of catalyst specified in Example 2 is brought to reaction in liquid butadiene in the autoclave, in such a manner that about 50% of the butadiene is reacted. Under these conditions the yield of n-octatriene rises to more than 60%, while the percentage of the higher oligomers drops to a total of about 30%. With reference to nickel, three times the amount of butadiene is reacted.
EXAMPLE 5 EXAMPLE 6 The reaction is performed according to Example 1, but instead of morpholine 100 g of aniline is used as the additive. In the course of 4 hours a reaction product (196.7 g) is obtained at 80C. having the following composition:
